The high finds its way to your body, where the physical buzz starts from the spine spreading its roots to offer a relaxing and soothing feeling.

Taste, smell and appearance

Thanks to its sweet genetic lineage, Runtz Auto offers a fruity taste profile. As the swirl of smoke touches the tip of the tongue, you will float away on a wave of intense sweetness, just like candy and bubblegum. On the exhale, the citrusy aroma lingers in the air.


Runtz Autoflo seeds are perfect for both rookies and expert growers. Cultivators can develop the seeds indoors and outdoors with a stable environment. The plant is not fussy nor bushy, yet regular pruning is vital to keep its best shape.

What are autoflowering seeds?

Back in the day, there used to be two major types of cannabis plants: indica and sativa. These are photoperiod dependent plants that start growing in spring and are ready to be harvested when days turn shorter, typically around fall. Indoor growers learned to imitate nature by manipulating this light cycle.

This changed in the early ’80s when breeders discover Ruderalis, a cannabis relative, which would automatically switch from vegetative growth to the flowering stage based on age, regardless of the light differences. When these Ruderalis genes were successfully combined with indica and sativa strains, autoflowering marijuana strains were born.

Since then, modern cannabis growers are spoiled with choices and speedy growth.

Autoflowering seeds have a lot to offer. For a start, they automatically flower after a certain amount of time has passed, they don’t just rely on photoperiod to start producing resinous buds. Autoflowering cultivars are also typically smaller in size, boasting strong, sturdy, and resilient genetics that are well capable of dealing with extreme temperatures and harsh weather.

Autoflowering plants are smaller but easier to grow and can be harvested much sooner than photosensitive plants.

Autoflowering seeds are ideal for those who are new to growing, those who grow in a small space, or those who want multiple harvests per season.

How to grow Runtz Auto seeds

When growing indoors, cultivators may use hydroponics and soil methods depending on their choice and resources. However, the soil method has the advantage since it can affect the flavor and aroma of this plant. Cultivators may install humidifiers and temperature systems to maintain the stable condition of the room.

Growing outdoors is the only option if you don’t have ample space inside the house. The outdoor setup has the advantage since the plant absorbs the natural light coming from the sun, and it will not cost that much. However, if you live in the Northern regions, you have to put the plants inside the house if there is bad weather.

Best climate to grow Runtz Auto seeds

If grown outdoors, a warm, sunny, tropical, or Mediterranean would be ideal for this strain.
